(Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 O. G. 757) 1 Claim.

The invention described herein may be manufactured and used by or forthe Government of the United States for governmental purposes withoutthe payment to me of any royalty thereon in accordance with theprovisions of the act of April 30, 1928 (Ch. 460, 46 st. L. 467).

This invention relates to improvements in copy holders and aims toprovide means whereby one or a plurality of superimposed sheets or pagesmay be secured in an upright manner and whereby one or a plurality ofthe secured sheets or pages may be held in an overturned position forthe exposition of desired or successive sheets. The device is adaptedfor holding sheets or pages in bound-book form and is particularlysuitable for securely holding a plurality of loose sheets in prearrangedsuperimposed relation for reading, reference and copying purposes.

The foregoing and other objects of the invention will be apparent from areading of the following specification and appended claim. An embodimenthaving the characteristics of the invention and by which the same may bepracticed is illustrated in the accompanying drawing in which:

Figure 1 is a front elevational view of the assembly;

Figure 2, an end elevation thereof;

Figure 3, a cross sectional view taken at line 3-3 of Figure 1; and

Figure 4, a partial perspective of the assembly illustrating a stack orbook of work clamped in original position, some of the elements beingsectionalized to illustrate their formation and operative relationship.

Figure 5 is a view similar to that of Fgure 4 but llustrative of theoperative position of the holding means; and

Figures 6, '7 and 8, sectionalized views taken on lines 66, 1-1 and 8-43of the clamping means of the assembly as illustrated in Figure 2.

The embodiment illustrated in the drawing for the purpose of explainingthe invention includes a pair of base members It) and H upon which aworkrest I2 is mounted, preferably with its face surface on an angleless than ninety degrees with respect to the bottom surfaces of the basemembers. Near the bottom of the workrest l2 there is provided aworksupport [3 which may suitably consist of a ledge or shelf-likemember, projecting from the face of the workrest at substantially aright angle thereto. At one edge of the workrest, preferably the left,means are provided for releasably engaging an edge or end portion of thework l4 and clamping the same against the workrest.

In the embodiment illustrated the clamping means includes a guideway l5secured to the workrest I2 at the left edge thereof and a guide l6slidably carried by the guideway. The forward end of the guide I6 isprovided with a compressor member I! which projects over a left endmarginal portion I8 of the face surface of the workrest. The compressormember I! is constantly urged toward the face surface of the marginalportion l8 by means of a pair of springs l9 secured under constanttension between the guideway l5 and the guide It. The slidable guide I6is provided with a projecting member 20 and the fixed guideway isprovided with a similar projecting member 2| intermediately of theprojecting member 20 and the compressor member ll. The slidable andfixed projecting members 20 and 2| are adapted to be engaged between anoperators fingers and when manually compressed, the compressor member I!is urged forward away from the face surface of the marginal portion I8of the workrest l2 for the insertion or removal of work [4 between thecompressor member l1 and surface l8, see Figure 4.

In order to hold a portion of the sheets of engaged work in overturnedposition, as shown in Figure 5, without removing or releasing the samefrom the clamp and in order to hold the work in open position to exposean intermediate page or sheet, I provide a fingerlike member 22 which ispivotally mounted above the work engaging surface of the workrest I2.The fingerlike member 22 is pivotally movable from a substantiallyvertical position in a clockwise direction suiiiciently far as to clearthe top of the work, for the turning of pages, and returnable to asubstantially vertical position to hold overturned pages. The fingerlikemember 22 is advantageously provided with a weight 23 which willautomatically return the member into a page-holding position whenreleased after having been manually lifted orbrushed aside as the pageis turned. To prevent the latter members from swinging as a pendulum andobstructing the View of the exposed page of the work, a stop 24 isprovided to block the counterclockwise movement of the page holdingmeans beyond a substantially vertical position.

In the operation of the device the projection 20 on guide I6 is urgedtoward the projection 2t on the guideway l5 by compressing the onetoward the other and since the compressor memher I! is carried by theguide I B, it is freed from contact with the surface of the marginalportion I8 for the insertion of work which will be engaged by thecompressor member upon releasing the compression placed upon theprojecting members 20 and 2|. As a page of the work is turned, thependulum may be brushed clockwise out of the way sufficiently for anoverturning of the page and then allowed to swing back into holdingposition, as illustrated in Figure 5.

Having described my invention and illustrated an embodiment whereby thesame may be practiced, what I claim is:

A copy holder comprising a tilted workrest as a back support for aplurality of bound or loose superimposed sheets or pages, a worksupportprojecting shelflike from the face of said workrest as a support forwork of the character named, work engaging means projecting over amarginal portion of said workrest, means normally urging said workengaging means toward said workrest marginal portion, means for manuallymoving said work engaging means reversely of its normally urgeddirection, and pivoted work holding mean manually movable andpendulously returnable for the receipt, holding and removal of partiallyoverturned portions of said work while engaged by said work engagingmeans.
